Large business enterprises typically benefit from reliable and secure communications both within the enterprise and with clients, partners and suppliers around the globe via the Internet. Middleware helps enterprises achieve this goal by integrating applications on different platforms or with diverse technologies. Asynchronous communication with a message queuing mechanism may ensure reliable communications among different parties. Message queues typically receive, store, and forward messages and requests for information and services. Message queuing is a method of process-to-process or application-to-application communication, such as communication between an application that services a user and an application that retrieves data from a database. Message queuing middleware implements various components to realize message queuing services. Applications may communicate by writing and reading application-specific data, or messages, to and from queues, without having a dedicated synchronous link between the applications. The asynchronous feature of the message queuing middleware allows the application to continue processing after making a middleware service request.
